Creates the
PmgCanvas object configured as - Multiple line graph defined by y values.
This preconfiguration can be activated when
creating a new Pmg object and is included in the group:
"/ Chart, functions".
This object contains embedded
PmgCanvas object named "
Dynamic". The item has the
variable val1,
val2 and
valX of the
String type containing values separated by semicolon. It is possible to connect it to the measured value of the same data structure by
data binding. The variables of the parent object are accessible in the
onDraw event by using the
pEvent.GetParentVar().
In the
PmgCanvas object, there are
variables minX,
maxX,
minY,
maxY,
spaceX and
spaceY. These variables define the scale range in both
x and
y axes and also the offset of axes from left and bottom edge of the
Pmg object.
Additional configuration variables are located at the beginning of
context itself, or at the beginning of designer's method. The following items can be set:
- colorScale color of ticks and scale descriptions
- nMajY number of main ticks on Y-axis
- nMinY number of minor ticks (between two main ticks) on Y-axis
- nDescPer specifies the quantity of displayed descriptors of main ticks (0 = no, 1 = every main, 2 = every second main)
- nMajX number of main ticks on X-axis
- nMinX number of minor ticks (between two main ticks) on X-axis
- colorArea background color of the graph rendering area
- colorGrid grid color
- nGridPer specifies quantity of displayed horizontal/vertical grid lines (0 = no, 1 = every main, 2 = every second main)
- nTextSize scale description text size
For embedded
Pmg object
- ctx.lineWidth = width of the rendered graph line
- ctx.strokeStyle = color of the rendered graph line
These configurators can be set before the preconfiguration is created:
| Object name | Name (identifier) of the Pmg object. It is used to obtain the Pmg object by the PmgObject.Items method.
This configurator sets the initial value of the Name property.
The maximum name length is 30 characters. This is a system name, so it must contain only alphanumeric and must not contain any diacritics (i.e. national dependent chars), empty string, spaces and the first character must not be a number. |

| Range from minimum (x) | Lower limit of X-axis |

| Range to maximum (x) | Upper limit of X-axis |
|---|
| Range from minimum (y) | Lower limit of Y-axis |
